Abstract
The fluid throughput of a conduit is increased without increasing the power requirements or the size of the conduit by affixing to the inner surface of the conduit at least one airfoil located with its leading edge facing into the flow substantially at the beginning of rectilinear flow. The airfoil advantageously has a body portion, a head portion, and a tail portion wherein the body portion has upper and lower planar surfaces defined by substantially parallel planes, side portions defined by substantially parallel side planes which are substantially normal to the upper and lower parallel planes, the head portion has a bulbous portion extending substantially below the lower parallel plane and the tail portion extends substantially below the lower parallel planes but not as far below as the bulbous portion.
